A simple method proposed by FCry (1912) partly over- comes these disadvantages by making use of a light bomb casing of a standard heat capacity and eliminating the water calorimeter. In this way the equilibration time is reduced to 5 min and the temperature rise is increased to 20-30'. In the method now WebbIn a bomb calorimeter, a 0.88 gummy bear is burnt. The temperature rose to 21.5 °C before settling at 24.2 °C. The heat capacity of the bomb calorimeter was calculated to be 11.4 kJ/°C by the manufacturer. Calculate the amount of heat released during burning per gramme of gummy bear.
